Low MTCT rates were observed over time. Lack of timely provision of antiretroviral drugs was the main limitation to develop all preventive interventions available nowadays. Nonsustained control of viral load could be associated with residual transmission.
BackgroundMaternal HIV coinfection is a key factor for mother-to-child transmission (MTCT) of HCV. However, data about HCV MTCT in HIV/HCV-coinfected pregnant women on combined antiretroviral treatment (ART) are scarce. This study assessed the HCV MTCT rate in the Madrid Cohort of HIV-infected women. MethodsRetrospective study within the Madrid Cohort of HIV-infected pregnant women (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012). Epidemiological, clinical and treatment related variables were analysed for the mother and infant pairs. HCV MTCT rate was determined. ConclusionMTCT rates of HCV among HIV/HCV-coinfected women on ART within the Madrid cohort were lower than previously described. However, rates are still significant and strategies to eliminate any HCV transmission from mother to child are needed.
BackgroundAn increasing number of perinatally HIV-infected women (PHIV) are reaching adulthood and becoming pregnant. Most PHIV women have been exposed to a high number of antiretroviral regimens, and they may have difficulties to achieve viral suppression. Psychosocial problems are not uncommon and could be an important barrier for treatment adherence. The effects of chronic HIV infection and long-term exposure to antiretroviral treatment of PHIV women cause concerns on the developing fetus. The aims of this study were to describe the prevention of mother-to-child transmission strategies in PHIV women and the infant outcomes in the Madrid Cohort of HIV-infected mother-infant pairs.MethodsAll PHIV pregnant women registered in the Cohort that gave birth from 2000 to 2015 were included in the study.ResultsTwenty-eight pregnancies in twenty-two perinatally infected women were registered. Most women were Caucasian and heavily treatment-experienced. Nine cases (32.1%) were at high risk of HIV mother-to-child transmission. Maternal HIV-1 viral load was detectable close to delivery in four women (14.3%). The management of these cases was described, and the treatment strategies were discussed. None of the newborns acquired HIV infection. Eight infants (28.6%) were small for gestational age.ConclusionsThis study included a large series of pregnancies among PHIV women attended according to a youth-centered care model. The challenges in the management of this population by health-care providers were described. Specific strategies to minimize perinatal transmission risks should be addressed in future collaborative studies.
BackgroundAntiretroviral therapy (ART) in pregnancy has resulted in a marked impact on reducing the risk of mother-to-child transmission (MCT) of HIV. However the safety of in utero ART exposure in newborns remains a concern.MethodsA multicenter prospective observational study of HIV-infected mother and their infants was performed in Madrid, Spain, from 2000 to 2009. Children had regular visits with clinical examination according to protocol until the age of 24 months. An abdominal ultrasound and an echocardiogram were scheduled during follow up. Birth defects (BDs) were registered according to European Surveillance of Congenital Anomalies (EUROCAT).ResultsA total of 897 live births from 872 mothers were included. Overall the birth defects prevalence observed was 6.9% (95% CI 5.4-9.1).The most commonly reported birth defects types were in genital organs and urinary system (19 cases, 30.6%) and cardiovascular system (17 cases, 27.4%). There was no increased risk for infants exposed in the first trimester to ARVs compared with unexposed infants. No significant associations were observed between exposure to any individual antiretroviral agent during pregnancy and birth defectsConclusionA higher prevalence of BDs was observed, higher than previously reported. In utero exposure to ART was not proved to be a major risk factor of birth defects in infants. However the relatively small number of patients is a major limitation of this study.
Background: An increasing number of women living with perinatally acquired HIV are reaching adulthood and becoming pregnant. Achieving viral suppression is challenging in this population frequently exposed to numerous antiretroviral regimens. This study describes the long-term outcomes of pregnant women living with perinatally acquired HIV in Spain.Methods: Descriptive, retrospective, multicenter study of the women living with perinatally acquired HIV who gave birth between January 2000 and December 2019 in Madrid. Epidemiological, clinical, and HIV-related data were collected from the first delivery to the end of the study period, including antiretroviral therapy, prevention strategies, and outcomes.Results: Sixty-three live births in 33 women were included. The mean number of pregnancies per women was 1.9 (range: 1-6). At first delivery, women's median age was 20 years (interquartile range: 18-23), 11 (33.3%) had been previously diagnosed with AIDS and 6 (18%) with mental health disorders. Forty percent became pregnant unsuppressed, whereas 81% achieved viral suppression at delivery. Treatment interruptions were common after delivery, as were losses to follow-up, with no positive effect of pregnancy on retention to care or the immune virological situation. Five women (15%) experienced a new AIDS event, and there were 2 deaths (6%) during follow-up. There was 1 case of mother-to-child transmission in a nonadherent woman in whom preventive measures could not be implemented.Conclusions: Pregnancy in this unique population of women living with perinatally acquired HIV poses particular challenges. Specific strategies, including a multidisciplinary approach, are needed to minimize perinatal transmission risks and improve outcomes during the postpartum period.
